"True, we have Our schools and teachers, our neophytes and 'Shaberons' (superior adepts) and the door is always opened to the right man who knocks. And We invariably welcome the newcomer; only, instead of going over to him, he has to come to Us. More than that, unless he has reached that point in the path of occultism from which return is impossible by his having irrevocably pledged himself to our Association, We never - except in cases of utmost moment visit him or even cross the threshold of his door in visible appearance."
